The ecflow_start.sh script will automatically set up and start your ecflow_server.

If you started an ecFlow manually then your server will start in a halted state.

In this case, you you will have to “restart” your server before you can use it.

In a halted state the server will not schedule any tasks.

...

Text

To check the status of the server, type the following at the unix UNIX prompt:


Code Block
languagebash
 ecflow_client --stats


Examine the output. If the ecflow_server is halted you would restart with:


Code Block
languagebash
ecflow_client --restart


Once the ecflow_server is running you have to start the suite by typing:


Code Block
languagebash
ecflow_client --begin=test


Python

Restarting and beginning the suite can also be done with the Client Server API.
Modify your client.py file and then run it.

  

Code Block
languagepy
title$HOME/course/client.py
import ecflow
 
try:
    ci = ecflow.Client()
    ci.sync_local()      # get the defs from the server, and place on ci
    defs = ci.get_defs() # retrieve the defs from ci
    if len(defs) == 0:     
        print("No suites in server, loading defs from disk")
        ci.load("test.def")
         
        print("Restarting the server. This starts job scheduling")
        ci.restart_server()
    else:
        print("read definition from disk and replace on the server")
        ci.replace("/test", "test.def") 
 
    print("Begin the suite named 'test'")
    ci.begin_suite("test")
 
except RuntimeError as e:
    print("Failed:",    e)


What to do

  1. Restart the ecflow_server
  2. Begin the suite , python3 client.py
